Question 22

Loops

Answer 22

A statement that is used to run certain instructions repeatedly. Useful for repeated sections of code

Question 23

For Loop

Answer 23

Carry out certain instructions numerous times. 3 basic parts: integer value, conditional statement the integer must reach to exit the loop, operation to modify the integer value after the instructions inside loop are completed. MUST set up exit condition or infinite loop will crash prog.
